Bootstrap Darkroom, modify Batch Manager via Personal Plugin not work

Hi,

I have the "Bootstrap Darkroom" installed and am following the directions in the wiki to try to add generating custom cached images to the Batch Manager. My server is low power and while can handle network traffic, generating thumbnails on the fly is quite slow so I want to generate the custom cu_e260x180 thumbnails ahead of time.

I pasted the code into the "Personal Plugin" of the "LocalFiles Editor". I verified that the content is saved in /plugins/PersonalPlugin/main.inc.php.

I have enabled the "Personal Plugin" under Plugins->Manage.

I logged out and in again but there was no new option in the Batch Manager. I also restarted the web server and php_fpm just in case something was cached.

I deleted all the compiled templates in _data/templates_c and verified they were recompiled. A quick search in the newly compiled template xxxxx.file.batch_manager_global.tpl.php shows that the new value isn't in there. Nor is the new code anywhere else in the

I hope someone has an idea of what I could be missing, or at least where to start looking. My gut feeling is that the Personal Plugin isn't working... but I don't know how
